`letteflfd Patent No. 105,393, dated July 12,1870.

#Tow-monheLSchedulefeferred to in these Letters Patent and making part of the same I, Enma WESTON, of teeny ftuffn, county l of E rie and Stateof New York,ba$ve inventedan Imy `provement in the Construction of Stoves, of which the l y following is a specification.v

Thevobjectof my invention is to` facilitate the c omf bustion of the "smoke and' uncousumed gases of the fuel; and y t l .I l

Itcousists in constructing the feed-door -or `mical windows, ork botlnwi'it-h slides or registers for the ad'- l y mission of air, in combination with a screen ot' wirecloth or perforated metal, situated on the Vinner partii l 4tion of said door or `windows, the same being made g l: withV `a double wall, leavingfa space or chamber beftweeu. 'f l 1 i y l jAs represented in the accompanying drawing- Figure l is a` sectional elevation of ajcylindrical 11igure2, an elevation ot' the inside of the door;

` and i w Figure 3, a like view of the outside of thesame.

A is the body oreylinder ofi-the stove, of whichiB' the tire-grate, Cthe ash-pit, and Dthe smoke-l plpe.

d l y The door E is situated atfsueh an elevation as to admit air tliroughhthe slide or openings Vj' fi alittle l above the ordinary levelot the burning fuel, `being nearlyias possible coincident, with the line ot separaf tion between the iiame and ignited fuel. L i l If xed'ames or. windowsyi, areA employed, they g l y are situated `at likeelevation at any convenient points,

i y or distauccsapafrt around the sides. l

" The door, as also thei window-frames, are preferaby cast `with double walls, as showmthe external one g 4being' provided with theair-openiugs j' f and slide h, the latter to regulatetheamount ,of air admitted, and

the interior plate having an opening of a size equaling` with advantage in the saving of fuel Y Witnesses: v

i the combined areas of the slide openings, the latter being covered by the wire-cloth Ic, or equivalent perforated material. y

There is an intervening chamber, l, which holds sutiicient quantity of air to be kept warm. p

The volume of air 'which passes freely through the slide-openings into the chamber after being heated'is A' subdivided into numerous minute jets, corresponding with the meshes of the perforated screen, and these myriad` jets intermingle'with thc'smoke andV gases which arise from the fuel, diffusing oxygenin their midst, thereby iguiting and consuming them before they escape into they` :smoke-pipe.V This method'of supplying air is 'shown by experience to he far more eifeetual than that of admitting an undivided volume,

partly, it is believed, .because the 'small` jets doY not sutiicientlylower `the temperature of the gases to prevent the ready combustion, and partly in consequence of the more general and uniform diusion obtained.

d ,The device described may be applied in various v ways to admit air tothe chamber of combustion at a point iu contact with or immediately abovethe surface of the re of stoves aud other heating apparatus,` and increased amount ofpheat. f

Iclaimf i 1 The employment, in stoves and other heating apparatus, of the air-induction chamber, `consisting of the chamber l, in combination with the wire-gauze distributer k, and graduating damper h, substantially as set'forthl In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. 1
